HOW IT WORKS

The Harris system is an efficient, durable battery-charging pelton
turbine. It is designed to produce usable household power from springs
and creeks that are too small to sustain the same level of useful power
from a conventional A.C. generating system. Because D.C. power can be
stored, the system is collecting power 24 hours a day, a little at a
time, to be used as needed.

The average American household (not using electricity to produce heat)
requires about 12,000 watt-hours a day, or about 500 watts on a
continuous basis. This can be reduced to about 300 watts by just
turning lights off when not needed. There are times, however, when as
much as 10,000 watts are needed, such as when a refrigerator or vacuum
cleaner is started. Because A.C. systems cannot store energy, they must
be sized to meet this peak load (requiring up to 40 times as much water
as a similarly useful D.C. system). Smaller sized systems save money.
D.C. systems are matched to extract power the way that nature delivers
it, slowly and steadily.

A 4-nozzle P.M. Generator-equipped turbine

Multiple nozzle arrangement allows much more water to impact the
runner, resulting in greater output at any head, and usable power
at a much lower head. All turbines include an output-optimizing
circuit allowing maximum efficience at any flow rate. Multi-nozzle
systems include a manifold kit and ball valves for each nozzle.

Pelton Type Runner

The pelton type runner is a lost wax cast of silicon bronze. The
wheel is 70 to 90% efficient, depending on nozzle size and head.
The bucket shape allows high efficiency for nozzles and provids a
flow range of over 100 to 1. The wheel has a hydraulic diameter of
just over 4.0 inches and each wheelis individually balanced.

There are two basic system configurations:

Mountain Cabin-DC Direct

The basic system is suitable where battery power can be used
directly. Cabins using 12-volt lights, portable radios, televisions,
and recreational vehicle type D.C. appliances are easily adapted to the
basic system.

Conventional House-110 volt

This configuration is suitable where higher output is needed and
110-volt, 60-cycle A.C. power is required to operate conventional
appliances. Both configurations are compatible with other D.C. charging
systems of 12, 24,48 volts, including photovoltaic cells, wind charging
systems and generator operated battery chargers.
